Machinery health monitoring – is supervision of its operation process changes in order to warn the personnel about unit reaching its critical state. It allows to make the most of the sudden failures gradual, due to their early detection and timely prevention.
Real-time monitoring – RT-Monitoring has a few essential differences from on-line/off-line monitoring. They consist in a strict regulation of an monitoring interval at the level of 10... 20% of an interval of the fastest development of malfunctions of the industrial complexes equipment.
That becomes possible on the basis of automatic systems with functionally uncertain structure, which does not depend on the equipment construction for the wide class of industrial complex units and contains a multilevel expert system. This allows to implement systems for real-time diagnostics and monitoring in case of prior uncertainty, when types of bearings, number of impeller blades, etc., can be unidentified, as well as to minimize static and dynamic errors and risk of failure omission.
The article dwells upon the main propositions of real-time health monitoring and the differences from on-line and off-line monitoring. There given rated correlations for certainty indexes and monitoring systems speed rate identification. The necessity of diagnostic features changes speed usage is shown. Definitions of monitoring, equipment condition danger, static error, dynamic error, zero-monitoring are given.
